Any advice/suggestions would be greatly appreciated. I have a 2002 stock XE with factory CD single/radio unit. For a while when loading the cd into unit it would hesitate and then pull cd in and play fine. Now it won't pull the cd in at all and closes a door into the unit. It also displays "ERR" on display. I only have 42,000 miles on vehicle and haven't used the cd player that much. What is the warranty on this player?

Thanks for any help.
